Definitions
- thermoplastics which is a polymer with aromatic structures included - known to have a very good black color due to laser radiation even without a discolourable Show aggregate.
- the different types of thermoplastic however react very differently; greater coordination in the process parameters and possibly also in the material modifications is needed.
- An optimally adjusted to the laser light Coloring is required, their light stability within the framework customary for the respective product class holds. Larger molded parts result in Limitations depending on the thermoplastic type in processing (Kunstscher 78 (1988), No. 8, pages 688 to 691).
- one can Adjust the plastic so that it is labeled with laser light can be, be it by choosing a well laser-inscribable Thermoplastic type or by incorporating one changing color due to laser radiation Aggregate. Both methods often lead to a product that is sufficiently contrasting with Let laser light be labeled. However, there will be more required technical properties of the material insufficiently fulfilled. A modular one Building a complete application profile, one of the requirements being laser markability is not realizable according to the state of the art.
- the invention is based, molding compounds Semi-finished and finished parts made of high polymer Material for marking and / or labeling using To provide laser light. In doing so, the marking / labeling a prescribed minimum value of the contrast ratio can be achieved.
- the laser markability should be independent of the material type and the set color of the molding compound.
- the molding compounds - and thus the products made from them Semi-finished and finished parts - made of polymer Material for marking and / or labeling using Laser light an aggregate contained in the visible spectral range (light wavelength 400 to 750 nm) no or only a weak one Has its own color and that under the influence of absorbed tem infrared laser light in the visible spectral range results in a marking with high color contrast, the laser light being absorbed by the aggregate and the additive is selected from 0.02 to 4.5 mass% copper hydroxide phosphate and 0.2 to 2.5 mass% molybdenum (VI) oxide.
- the color contrast can arise, for example, that the aggregate under the influence of absorbed laser light changed to a colored product.
- the wavelength of the laser light is in the infrared range above 900 nm.
- a laser for example an Nd-YAG laser (wavelength 1064 nm) be used.
- CHP Cu 3 (PO 4 ) 2.
- Cu (OH) 2 ; libethenite is e.g. B. described in Gmelins handbook of inorganic chemistry, volume 60, part A, page 175 and part B, pages 920 to 925.
- a CHP which has been prepared in accordance with EP-0 143 933 is preferred.
- Parts are understood to mean parts by mass.
- the contrast ratio K is measured according to the method known from the literature. For dark characters on a light background, it is defined as the quotient of background luminance to character luminance.
- an Nd-YAG laser with a wavelength of 1064 nm in pulse mode, a pulse frequency of 8 kHz and a laser power of approx. 5 W is used for labeling semi-finished products and finished parts.
- the illuminance in the labeling plane is approx. 100 J ⁇ cm -2 .
- the dark marking generated in each case is clearly visible; their surface quality hardly differs from the quality of an unexposed area.
